In this paper a very general method is given in order to reconstruct a periodic function f knowing only an approximation of its Fourier coefficients.

Algebrability of the set of non-convergent Fourier series

We show that, given a set E ⊂ 𝕋 of measure zero, the set of continuous functions whose Fourier series expansion is divergent at any point t ∈ E is dense-algebrable, i.e. there exists an infinite-dimensional, infinitely generated dense subalgebra of 𝓒(𝕋) every non-zero element of which has a Fourier series expansion divergent in E.
